MACHINE FOR OPERATING UPON THE BOTTOMS 0F BOOTS AND SHOES.

Application led November 18, v13122.

To all whom t may concern Be it known that I, CHARLEs T. CAHiLL, a citizen of the United States, residing at Boston, in the county ofSufolk and State of Massachusetts, have invented certain Improvements in Machines for Operating Upon l the Bottoms of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts. in the severall this practice involves the expenditure of* considerable time and labor in the performance upon the same portion of the shoe of two distinct and to some extent similar op-1 erations which could be saved by performing the two operations together at the same time and by the use of the same machine.k

The object of the present invention isV therefore to provide means whereby the operation of impressing or imprinting a designation on the sole or other part .of the shoe may be performed at the same time as, and in conjunction with, another operation as, for example, the breasting of the heel- An important feature of theinvention consists in the combination with a shoe support, of means for breasting the heel, and means for imprinting or stamping a design or designation upon some `portion of the shoe bottom, for example, the shank, the breasting means and the `die of the stamping means being respectively positively and yieldingly operated. The operations of breasting and stamping preferably occur during the same operative cycle of the machinev and'may lconveniently take place simultaneously and while the lshoe is in the same position on the support.' u

Another feature of the invention consists Specification of Letters Patent. Y

in means, operated .upon contact with the shoe shank, for releasing the breasting means and the stamping means from theiroperating mechanism. In the construction shown, the breasting means 'is mounted on a slide which is reciprocated to effect the breasting operation, and means is provided for releasing the slide from its operating means when the breasting means has finished breasting the heel. The stamping means may be operated-by the breasting means and, as shown7 is mounted uponthe slide which carries the breasting means. It follows, therefore, that the stamping means is released from .its operating means simultaneously with-theV re- 4 lease of the breasting means.

Another feature of the invention consists in means for operating the die or stamping means by power and releasing it whenthe die has yielded` a predetermined amount. As shown, the die is resiliently connected with they power operated'knife slide and extends in advance of the knife. The stamp, therefore, comes in contact with the shank before the knife finishes the breasting cutthe resilient connection yielding a predetermined amount before the knife and the die are simultaneously released after eachhas performed its work. Thevdie, by reason ofy its resilient mounting, which preferably in'- cludes a stiff-spring, may-be brought into type as that disclosed' in an-appl'ication for United States Letters Patent Serial No. 686,042, filed March 25, '1912, to which-reference may be had for a fuller description of the general organization of the machine. The machine comprises a frame 2 in which a knife carrier 4 is arranged to slidevertically. The usual knife actuating slide is mounted in a frame back of the knife carrier or slide 4f and is normally connected thereto. Automatic mechanism is provided for disconnecting the knife carrier 4 -from the actuating slide upon contact of a bunter 6 with the shank portion of the shoe, when a knife 8 mounted on the carrier 4 hasl cut through the heel. The shoe is supported by a jack 10 and is located relatively to the knife and held in position during the breasting` operation by a gage tread plate 12 which isdepressed toward the heel by the usual connection to a treadle,'not shown. The'shoe i stamping mechanism vwhich is combined with the breasting machine by this invention is mounted upon a bracket 14' which is bolted to the knife carrier on slide l at 16 for actuation thereby toward and from the shoe. The bracket 14 is shaped to provide bearings at 1 8 and 2O for a rod 22 which is splined in the said bearings for vertical movement. The lower end of Athe rod 22 carries 'a block 24: on which ak die 26 is mounted for move'- ment about an 'axis 28 extending' transversely of the shoe. As a further means of preventing rotation of the rod 22 about its axis, a pin extends from the block 24 through a hole in the bracket 14. A portion of the rod 22 lat 33 is threaded and is provided with a capstan nut 34 between which 'and "the bracket is located a strong helical spring 36. The spring 36 holds the rod 22 depressed with a clamp nut 88 which is threaded on the upper end ofthe rod in contact with th bracket 14.

ln the operation of the machine the shoe is placed upon the ack 10 which swings about a pivot near its lower en d, not shown, and the shoe is Aswungbeneath the plate 12 ywhich is then depressed by the treadle against the heel and thevheel is located Ywith respect to the forward edge of the plate which 'indicates the position of the out to be made by" the knife. The treadle is then further fdepressed to start the machine, whereupon the knife carrier lcarrying the bracket lis depressed. After the knife 8 has begun to cut the heel, but prior to the contact of the bunter 6 with the shank 'of the shoe, the die 26 comes into contact with the tread face of the shank. Continued movement of the knife carrier forces die 26 into the leather, the spring- 36 yielding, if necessary, topermit the knife to complete its stroke. Upon the completion of the knife stroke the bunter 6 cont-acts with the shank and disconnects the knife carrier from its actuator whereupon the knife 8 and the die 26 return to gether to their normal position, as shown. The tread plate 12 is then released and the shoe removed from the jack.

Having described my invention, what I claim as newand desire to secure by Letters Patent of the United States is 1. In a machine of the class described, the combination of a shoe support, a reciprocating slide, means for breastingthe heel of a shoe, means for stamping the shank of the shoe, both said means being actuated respectively unyieldingly and yieldingly by said slide, and means operating upon contact with the shoe shank for leasing the breasting means and the stamping means from actuation by the reciprocating slide.

2. A machine of the class described having, in combination, a work support for sustaining a shoe, a knife for breasting the shoe heel, operating means therefor, a die, connections between the die and the knife operating` mechanism for effecting a die impression upon the outer face of the shoe bottoni during the 'operating cycle of the breasting knife, and means for automatically "eifecting release of the knife and die simultaneously when the end of their operative stroke is reached.
